RADIANT-ENERGY RECEIVER.

Application filed May 11,

To all whom z'tdnay concern: Beit known that I,-, HENRY (i. SAM,

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Radiant-Energy Receivers, of which the following is a 'full, clear, concise, and exact description.

- My invention relates .to receivers for. ra-

- employ a crystal body and energy conducting wire at one 'face of such body. 7 V j The invention has for its object the provi sion of an improved mounting for the wire whereby it may be adjusted into effective relation with the crystal body. In 'carrying out the invention I employ a rod that 3 curved where 'it' engages the carries the wire, a block supporting said rod, a support formed with a seat that receives said block that is capable of adjustment onsaid support, and a spring which presses'the block upon the support to hold it in its various adjustments. I

In the preferred embodiment of the invention the support for the block is in the form, of a hollow post. which has a-spherically curved seat at its upper end that lie-'- ceives the block which isalso spherically post to be capable of adjustment in all directions upon the'seat. The spring that presses the block upon its support is preferably a coiled spring within the hollow of the post and which serves to connect the block and post whereby the block and post are maintained in assembly while permitting the wlde range of adjustment for the block. without the necessity of manipulating any device for 50 in which maintaining the adjustment, the spring also performing this latter functwn. The rod Is in sliding relation to the block that carries it so that th wire may be ad usted with respect to the crystal body not only by adjustment of the block which carries the wire supporting rod but also by adjustment of thisrod. I will explain my invention more fully by reference to the accompanying drawing Fig.1 shows the preferre d em-' bodiment of the invention withsome of the arts shown in sectional elevation and some 1n full elevation; and Fig. 2 is aplan view 19:22. Serial No. 559,990.

Like parts are indicated by similar characters of reference in both figures. Any suitable form of mounting, such as the plate 1 of insulation, maybe employed for the parts that comprise the invention. .The crystal body '2, such as galena, is pro- /vided upon the crystal mounting 3 which is formed; with a threaded stem 4. The plate 1 is clamped between the base of the mounting 3 and the nut 5 that is screwed upon the threaded stem 4. A hollow post 6 is similarly formed with a threaded extension 7, the plate 1 being clamped between the base of the post 6 an the nut 8 which is screwed upon the post extension 7. -The post is hollow from end to end .and is formed with a spherically'curved seat at its upper end to receive a block 9- which is' preferably in the-form of a ball, the lower side of the block, at least,.being of spherical curvature.

Th block is capable of adjustment in universal directions u on the post and is maintained in assembl each of its adjustments by means ofa coiled spring, 10 which is connected at one end with the stem 11 provided upon the element 9 and at its other end with a stirrup 12. The spring is under sufiicient tension to hold the block 9 upon the upper end of the post 6 and the stirrup 12 against-the bot tom end of the post.

formed with a' diametrical bore in which The element 9 is the rod 13 has snug sliding engagement with of my invention, I do not wish to be limited 100" to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having'thus described my invention I claim as new and desire-tosecure by Leticev ters Patent the following:-

1. In a crystal detector, the combination with a crystal body; of a wire ending at one face-of the crystal body; a rod carrying Circuit wires 15 and 16 are any suitable way with the block. that carries the rod shown 65 in section. said wire; a block supporting said that is in sliding relation to the block; a hollow post formed with a spherically curved seat at its upper end that receives said block that is also spherically curved where it enpost to be capable of adjustment;

gages the and a coiled spring connecting the block and post and within the hollow of the latter and serving to press the blockupon the post and hold it in its various adjustments; I

2. In a crystal detector, the combination with a crystal body; of a wire ending at one face of the crystal body; a rod carrying said wire; a block supporting said rod; a

hollow post formed with a spherically curved seat at its upper end that receives said block that is alsospherically curved where it engages the post to be capable of' ad ustment; and a coiled spring connecting.

the block and-post and within the hollow of the latter and serving to'press the block upon the post and hold it in its various adjustments.

3. In a crystal detector, the combination connecting the block and post and within the hollow of the latter and serving to press the block upon the post and hold it in its various adjustments.

4. In a crystal detector, the combination with a crystal body; of a Wire ending at one, face of the crystal body; a rod carrying said wire; a block supporting said rod; a hollow post formed with a curved seat at 'its upper end that receives said block that is also curved where it engages the post to be capable of adjustment; and a coiled spring connecting the block and post and within the hollow of the latter and serving to press the block upon the post and hold it in its various adjustments.

5. In acrystal detector,.the combination with a crystal body; of a wire ending at one face'of the crystal body; a rod carrying said wire; a block supporting said rod-that is in sliding relation to the block; a hollow post formed with a seat at its upper end that receives said block that is capable of adjustment on'said post; and a coiled spring connecting the block and post .and within the hollow of the latter and serving to press the block upon the post and hold it in its various adjustments. I

In witness whereof, I hereunto subscribe my name this 6th day of May A. D., 1922.
